Runs great for about 45 minutes then quits, new fuel filter, new coil, electronic ignition. Nothing helped. I need advice and guidance. Thanks

forgot to mention, if it sits for a hour will start right up.

When it quits pull the plug in the carb and see if you continue to get gas for a few minutes. If so you can rule out it being a fuel problem.

Learn to trouble shoot then parts NEVER the other way around.
#1 run it till it dies. Then check for a good blue/white spark that will jump a 1/4 inch gap at the center wire of the cap and at the plug wires. No spark or weak spark you have a problem in the distributor
#2 pull the carb drain plug and make sure you have a good steady flow of gas that will fill a pint jar in less then 3 minutes

Old has the right idea and I would check your gas cap to see if it is vented. Maybe it stops because it cannot get gas because of a vacuum. After it sits awhile it releases the vacuum and will run again for a while. A quick check would be run it with the caps loose.
